我们在学习兄弟单位先进刀具的基础上,结合我厂小孔加工的实际生产情况,试验和应用了圆孔切压螺旋拉刀。经过一段时间的生产实践,效果良好。采用拉削工艺不但可以提高孔的加工精度和生产效率,而且工序便于集中,给自制专用设备准备了条件。对于这种加工方法,我们也正在摸索中,没有成熟的体会和数据,只能把我们对圆孔切压螺旋的初步认识介绍如下。 Based on the study of advanced knives of our brother unit, we combined with the actual production of small hole machining in our factory, we test and apply the round hole cutting and pressing spiral broach. After a period of production practice, the effect is good. The use of broaching technology can not only improve the hole machining accuracy and production efficiency, but also easy to focus on the process, to prepare the conditions for the preparation of special equipment. For this processing method, we are also groping, there is no mature experience and data, only to our understanding of the initial understanding of the hole cut spiral as follows.
